To all whom 'it may concern:

Be it known that. I, PETER H. MURPHY, a citizen or' the United States. and a resident of the city ot' Pittsburg, count of -Allegheny. and State of. Pennsylvania, have invented a new and useful Improvement in Car-Roofs, oi which the following is a specification.

My intention relates to car roofs, and has for its principal objects to fasten the metal roof sheets in such a way that said sheets shall be movable relative to the sheathing and shall be substantially free from bending and tearing stresses at the eaves; also to guard against the admission of water under the metal sheets at the eaves without binding the ends of the sheets or haring to turn them down a considerable distance over the caves; also to make the seam caps contribute to the strength of the ear structurefand to attain other advantages hereinafter appearing.

The invention consists principally .in providing the root` sheets with retainingstrips `close to the eaves and adapted to interlock with fasteners secured to the substructure. It also consists in providing the roof sheets with nailing strips adapted to secure .the root sheets in placc'to permit them to accommodate themselves without strain at the eaves to the various distortions of the substructure.

It. also consists in .seam caps adapted to hold down the roof sheets. to protect the seams, to :weonnnodate the required movements thereof, and toscrve as secondar)7 outside carlines.

The invention also consists in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specitication, and wherein like symbols refer to like parts wherever they occur. Figure l is a cross section of a portion ot the car embodying my invention; Fig. 2 is a plan view of the inner portion of the seam cap illustrated at 'the left side of Fig. l; Fig. 3 is a plan View of the seam cap 'illustrated at the right side of Fig. 1, and

of the adjacent portion oi the left hand seam cap; Fig. 4 is a cross section of the seam eap on the line #Lt- 4 of Fig. 2; Fig. 5 is a pcrspective view of a nailing strip; Fig. 6 1s a rspective view 'of a retainin strip, which is mounted on the, underside oa root` sheet;

.Figa 7 is a detail perspective view of the outer end portion of a roof sheet; Fig. 8 is an end elevation of a seam cap; Fig. 9 is a detail sectional view through a roof seam and the adjacent portions of the roof sheets; Fig. 10 is a perspective detail of the flashing strip; Fig. ll is a cross sectional view ot' a. car embodying a moditiedform of my inventiong'Fig. l2 is an end view of the seam clip illustrated in Fig. l1; Fig. 13 is al detail of the flashing strip illustrated in Fig. l1 and, Fig. 14 is a plan view of the seam cap illustrated in Fig. 1l.

The woodwork o' the car comprises side plates 1,*side sheathing i, roof sheathing 3, a ridge pole si, and a fascia Metal root1 sheets G lie, flatwise or; the roof sheathinr and are connected by any suitable joint. t which will permit movement thereof relative to the roof sheathine'. As illustrated in the drawing, the side margins ot the sheets have rebent tlanges `which overlap each other to form ribs or seams; and the ridge ends of the sheets are provided with similar rebent anges which interlock to forni scams S at the ridge. The outer end of each sheet has retainingr strips S) mounted on the underside thereoic close to'and parallel with the eaves. Preferably, these retaining members are strips of sheet metal whose ends are riveted or otherwise secured to the roof sheets, the end portions of such retaining strips being offset upwardly so as to space theluidv, portion thereof from the body of the root sheet. The roof sheets are held in place by nailing strips 10 which are secured to the body of the car and are flexibly connected to the retaining strips. In the construction illustrated 1n the accompanying drawing, these nailing strips are slicets ot' metal which are rebent along one side to form a continuous loop 11 parallel'with the body. The body of the nailing strip lies between the metal roof sheet 6 and the retaining strip Si. with the looped end 11 under- 100 neath said retaining strip. The outer Side 12 of the nailing strip is bent.` downwardly and nailed latwise to the eaves. The nai.- ing strip thus constitutes-'t flashing as well as a meaps for securing` the sheet in position. 105

Under normal conditions, the edges of the retaining strip are spacedjrom the bend of the loop 11 and from-the downturned por tion orflange 12 of the nailingstrip, respectively, and the ends of themalll12-stip 959.119

iwv-n,

spaced from the offset portions of the retaining member. In consequence-of .this arrangement, the roof sheets are reeto more portions ot' the roof.

groove 1T therein of sutlieient height and.

ing stripl, whose downturned portion is nailed tlatwise against the caves and whose 'upper portion extends inwardly a suflicient distance to protect the woodwork from the weather. In order that the end portions of the sheets may lie in the plane of the body portion, the marginal portion of the woodwork has a rabbet lt formed therein of suliicient depth to accommodate the looped nail-I ing strip. The outer edges of the roof sheets project slightly beyond the nailing strips and are bent downwardly suliciently to forni a drip edge l5. In order to protect the metal portions of the roof against scraping, tlie'lowcr portion of the fascia is made thick enough to project beyond such metal The roof seams 'i' are protected by seam caps 1G. .ts illustrated in-A Figs. 1, 2 and 3, the body portion of the seam cap extends from caves to ridge and has a longitudinal width to accommodate the seam. This lon gitudinal groove widens gradually from the ridge to the caves to perniitllie oiiterportions of the root' sheets to move. laterally tlierein that is to say, longitudinally of the car. The outer end 1S of the scam cap is turned downwardly beyond the roof sheets and is fastened tothe side of the car. Preferablv. the material surroiniding the bolt or nail hole is raised or turned inwardly to forni an annular rib 1.) which may be driven into tbc woodwork and constitute a lining for the outer portion of the bolt or nail hole. .\t the ridge, the scam cap is provided with a transverse groove 20 adapted to siraddle the ridge seam of the root' sheets. Une of the scani caps overlaps the other at the ridge and projects a slight distance beyond the ridge seam, sai-b projecting portion haring a longitudinal groove adapted to accommodate the underlying roof seam T. At the iiitersection ot the longitudinal and transverse grooves of the seam cap a hole 21 adapted to receive a bolt which extends through the ridge pole. U

In the construction illustrated in I? 1g. 1, the seam cap is made integral and preferably of sheet metal; and' 'the seanrcaps on one side of the roof are separate from those on the opposite side.

In the construction illustrated inlfig. 11, the Seam cap is made of parts fastened together. In :this construction, a corner cap, made preferably of malleable iron, is provided with two intersecting grooves adaptf ed to receive the ridge seam and the transrerse roof seams. On the fasciasareinonntet. suitable clips ,having groovcd hoods or clips which are turned inwardly over the ends of 'the' respective seams. The corner cap and the two eaves clips are fastened securely together by means of body members riveted thereto and provided with longitudinal grooves adapted to accommodate the transverse root: seams.

diiial grooveswidcn toward the eaves. By this construction, the seam caps extend from eaves to eaves and contribute materially to the strength of the car structure, especially by functioning tie rods to prevent the spreading of the sides of 'die car.

In the construction illustrated in Figs. l1 and 13, the llashing strip 22 has its lower portion .23 narrowed and`elongated. This elongated portion extends through an elongated slot 24 provided therefor in the downtuined portion of tlieseain cap or o the seam clip 25, which may be an independent ieee. The elongated end portion of the ashing 1s bent downwardly around the.

looped edge of the fascia and is nailed to the bottom thereof or otherwise suitably 'fastened. as illustrated in Fig, 11. In this construction, the flashing is preferably nailed to the top of the fascia also. It is one adyantage of. this construction that the tlashing serves to hold vthe seam clip in place in case the normal fasteners for said clip shall become loosened and the clip become otherwise disensraged.v i

Obviousv, my device admits of considcraole modification without departing from my invention, and therefore Ldo not wish 4 As in the case of the .seam caps above described, the longituto be limited to the exact construction shgyvn and described.

.Vhat I claim as my invention and desire to secure by Letters Patent is:
